Question

HELP PLEASEEE IM BEGGING YOU

One year ago, a tiger cub was 5 feet shorter than its mother. However, it grew 2 feet, and now it’s mother is only twice its size. How big was the tiger cub one years ago?
This is algebra 1 btw...

Answer 1

The cub was 1 ft long a year ago.

Explanation:

The tiger cub was 1 foot long a year ago.

One year ago, if the tiger cub was 1 foot:

1 ft = Cub

1 + 5 = 6 = Mother

Now:

1 + 2 = 3 = Cub

6 = Mother

The mother is now only twice as big as the cub, meaning that this solution is correct.

Solution using algebra:

One year ago:

x = Cub

x + 5 = Mother

Now:

x + 2 = Cub

x + 5 = Mother

We know the mother is now only twice as big as her cub.

2(x + 2) = x + 5

2x + 4 = x + 5

2x - x = 5 - 4

x = 1

Hope this helps!

Answer 2

One year ago, the cub was 1 ft

Explanation:

One year ago:

The height of Mother tiger = x feet

Height of cub = x - 5

Now,

Height of cub = (x - 5) + 2 = x -5 + 2 = x - 3

Height of mother = Twice the cub size

x = 2*(x - 3)

x = 2x - 6

x + 6 = 2x

6 = 2x - x

6 = x

The height of Mother tiger = 6 feet

Height of cub = 6 - 5 = 1 feet
